Offset Notes dialog allows you to adjust all the notes or the selected notes time offsets.
Right click on a MIDI clip or MIDI data in the Piano Roll and select "MIDI Editing" followed by "Offsets..." This brings up the Offset Notes window.
The options are:
•1/4 triplet notes
•1/8 triplet notes
•1/16 triplet notes
Choose the number of 1/4 notes or 1/8th notes or whatever you have chosen. For example, you could choose 3 - 1/8 Notes to offset the notes by.
All or Selection
Choose whether to adjust the selected notes or all the notes in the current virtual instrument clip.
(This is only an option if the dialog was invoked on the piano roll editor.)
